NTU researchers predict that a new kind of quantum jump in atoms, called a toroidal transition, can lead to unexpected forms of light emission.

Building A Michelson Interferometer
The Michelson interferometer is a device that uses optical intereference to measure extremely small distance variations. First invented in the late 19th century, it remains in active use today; in 2017, the Nobel Prize in Physics was awarded to the LIGO experiment for using large-scale Michelson interferometers to detect gravitational waves. Recently, our team at SPMS set out to construct a Michelson interferometer for science education and outreach.
Quantum Foucault Pendulum
Publishing in Nature Communications, Associate Professor David Wilkowski and co-workers report on the realization of a quantum mechanical version of a Foucault pendulum, using a cloud of cold atoms.
